/// Safe / Visc
Once the "VISC / SAFE" has been set to "VISC", the viscosity trend value (12)
will be shown on the display. The torque trend measurement is used to
deduce the change in viscosity of the reaction medium. The devices are not
designed to measure absolute viscosity. They only measure and display the
relative change in the viscosity of the medium from a starting point specified
by the user.
Once the speed of the motor and magnetic rod in the medium have sta-
bilized to the target speed, the viscosity measurement is started at 100 %.
Consequently, an increase in the measured torque trend is indicated by a
value > 100 % and a reduction in values < 100%.
The value can always be reset to 100 % by pushing the „Menu" button (E)
for 2 seconds.
Note! ( )
Torque trend measurement only works for a constant set speed for
the duration of the measurement. As a result, intermittent mode
cannot be used in conjunction with torque trend measurement.
The current control variable is saved as the reference 100 % ΔP and shown on
the digital display. The change in the viscosity is then shown in %.
When on the "VISC" screen, the screen will switch to "SAFE" if the adjustment
of the safety temperature is activated, during which you may set the safety
temperature and the screen will switch back to "VISC" once the setting is done,
otherwise it will switch back to "VISC" after 2 seconds.
/// Factory reset
The menu item "Factory reset" allows the user to reset all the system
settings to the original standard values set at dispatch from the factory
(see "Menu structure").
